Winchesteer Bay/Umpqua Jetty Swell Statistics, All Year: Surf with Light or Offshore Winds

This image shows only the swells directed at Winchesteer Bay/Umpqua Jetty that coincided with light winds or offshore conditions over a normal year. It is based on 34628 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours illustrate increasing wave sizes. Blue shows the smallest swells, less that 0.5m (1.5 feet) high. Green and yellow show increasing swell sizes and red illustrates biggest swells greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how often that size swell occurs.

The diagram indicates that the prevailing swell direction, shown by the biggest spokes, was W, whereas the the prevailing wind blows from the NW. The chart at the bottom shows the same thing but without direction information. For example, swells larger than 1.5 feet (0.5m) coincided with good wind conditions 24% of the time, equivalent to 88 days. Expect open water swells to exceed >3m (>10ft) 2% of the time (7 days). Taking into account the fraction of these swells that coincided with forecast offshore winds, and given the fact that Winchesteer Bay/Umpqua Jetty is exposed to open water swells, we estimate that clean surf can be found at Winchesteer Bay/Umpqua Jetty about 24% of the time and that surf is messed up by onshore wind 70% of the time. This is means that we expect 343 days with waves in a typical year, of which 88 days should be surfable.

IMPORTANT: Beta version feature! Swell heights are open water values from NWW3. There is no attempt to model near-shore effects. Coastal wave heights will generally be less, especially if the break does not have unobstructed exposure to the open ocean.
